"I have neither done nor seen a study which supports the conclusion that the term "female," when used as a noun is usually intended as a condescending, harsh, or critical term."

Wait - so that's it? You haven't performed a study on this issue nor have you read anything about it, so you're dismissing it? Luckily, I have been studying things like this and other microaggressions (and studies surrounding them) for several years now, and trust me - it's a thing.

There's a reason why studies are thin on the ground though - because women are told not to 'make a fuss', that there are 'bigger problems' we should be focusing on etc etc. We also get massive eyerolls (and other forms of dismissal) when we take a stand like Raven here.

But, since you've undertaken to study it now, I'd advise concentrating on women and not men. What would be the point of saying something to a woman and then asking a guy whether or not he found it unacceptable? With microaggressions like this, it goes straight over the heads of most men, so no, men don't count here if understanding the impact of the word on women is your objective.
